Complexity of quantum impurity models

Sergey Bravyi, IBM Research

I will discuss classical and quantum algorithms for simulation of quantum impurity models. Such models describe a bath of free fermions coupled to a small interacting subsystem called an impurity. Hamiltonians of this form were famously studied by Anderson, Kondo, Wilson and others in 1960s.

This is the tenth and final of the Intellectual Property (IP) Management Lunch and Learn Lecture Series. We are bringing in thought leaders in the protection and management of intellectual property, including many years of experience in relevant areas of information technology.

This session will be led by Neil Henderson and Tom Hunter.

Constraint Propagation Games

Zhengfeng Ji, University of Technology, Sydney

Constraint propagation games are simple extended nonlocal games that are motivated by the propagation checking of quantum computation and have found powerful applications in the study of quantum proof systems recently. In this talk, we will introduce their definitions and basic properties, demonstrate their uses in larger games as building blocks, and illustrate the method that turns them into nonlocal games.

Characterizing drift qubits

Timothy Proctor, Sandia National Laboratories

It is essential to benchmark and characterize real-world qubits in order to understand whether they are of sufficient quality for quantum information tasks, and if they are not, so that they can be debugged. Many techniques are designed for qubits that stay constant in time, but in reality almost all qubits suffer from some form of time-dependence.

Efficient quantum memory in naturally trapped Rare-Earth ions

Mahmood Sabooni, IQC

The ability to map, store quantum states of light (e. g. single photon) to matter and later retrieve is one of the important building blocks of quantum information processing. Such a device is called a quantum memory for light.

We give a framework for studying arbitrary quantum operators that are being controlled by an ancilla. We show that controlled quantum operators can be used for searching. Controlled quantum operators can simulate existing search methods such as Grover's algorithm, amplitude amplification, quantum interpolated walks, and Szegedy's and Ambainis's quantum walks.

The Women in Physics Canada (WIPC) conference, hosted by the University of Waterloo, Faculty of Science, Department of Physics & Astronomy and the Institute for Quantum Computing, will bring together early career scientists to present their research and hear plenary talks from leaders in physics.

We welcome attendance by people of all genders.
